Definitions
- the invention relates to an evaporator body for a Evaporator of a vacuum evaporation system, which consists of at least two in a row by one Connection on one end face electrically conductive coupled evaporator boat exists.
- Evaporator body of the above type is in the German Patent 40 16 225 described.
- the invention is based on the problem of an evaporator body to develop with at least two evaporator boats, where the connection of the evaporator boats is as simple as possible and becomes a rigid, unchangeable Alignment of the evaporator boats to each other leads.
- This design is between the evaporator boats no additional connecting part to create the connection required.
- There the projection has no arc-shaped surfaces instead of an articulated connection, a rigid connection, so the orientation of the evaporator boat to each other is determined by the connection.
- the projection as formed by an upper and lower inclined surface horizontally extending wedge is designed and the recess accordingly by two from above and from below Areas leading obliquely into the end face are limited.
- This design makes play in the area of connection avoided. Furthermore, it can be achieved that the entire connection area is sufficiently high, axial Forces can be transferred, what a reliable Plant the parts and thereby to a low electrical Contact resistance leads.
- connection area To further improve the current flow through the connection area it helps if between the jump of an evaporator boat and the recess of the another evaporator boat arranged a graphite foil is.
- FIG. 1 shows end regions of an evaporator body 1 two evaporator boats connected to each other on the face 2 and 3. This connection is made by that the evaporator boat 2 with a projection 4 in a corresponding recess 5 of the evaporator boat 3 takes effect. Between the projection 4 and the recess 5 is a graphite foil 6 in this exemplary embodiment arranged. In the upper side of the evaporator body 1 there is a cavity 7, which over the connection area both evaporator boats 2, 3 away leads and in which the metal to be evaporated is introduced becomes. The evaporator body 1 thus has a single continuous excavation 7.
- FIG. 2 shows a view from the right of the evaporator boat 2.
- this figure 2 there were two sloping surfaces 8, 9 positioned, which limit the projection 4, so that this is a horizontally extending wedge forms.
- the wedge tip an angle of about 90 °. In practice, this must be flattened be so that the wedge surfaces 8, 9 against the corresponding in Figure 1 positioned surfaces 10, 11 of the Fit recess 5.
- FIG. 3 shows the evaporator boat 2 as a whole. Again, the wedge-shaped projection 4 and the cavity 7 in the top of the evaporator boat Second
